The streaming services will continue to nickel-and-dime us all — because they can
As online services fight for every single dollar — sometimes by less-than-scrupulous means — the only way we can fight back is by canceling......»»
Scientists study the behaviors of chiral skyrmions in chiral flower-like obstacles
In nature, the collective motion of some birds and fish, such as flocks of starlings and shoals of sardines, respectively, can generate impressive dynamic phenomena. Their study constitutes active matter science, which has been a topic of great inter.....»»
Neural network assisted high-spatial-resolution polarimetry with non-interleaved chiral metasurfaces
Polarimetry plays a key role in wide applications from remote sensing and astronomy to biology and microscopy. Traditional polarimetry systems are equipped with a set of polarizers, waveplates, beam-splitters or filters, making the systems bulky and.....»»

Strategies for enhancing the performance of nickel single-atom catalysts for the electroreduction of CO₂ to CO
Electrocatalytic reduction of carbon dioxide (CO2) is considered as an effective strategy for mitigating the energy crisis and the greenhouse effect. Among the multiple reduction products, CO is regarded as having the highest market value as it is a.....»»
Physicists develop novel concept for detecting chiral molecules
In contrast to conventional mirrors, light can be reflected on surfaces known as metasurfaces without changing its polarization. This phenomenon has now been proven by physicists at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) and the Ma.....»»
Hubble observes an askew galaxy coaxing star formation from its partner
Arp 300 consists of two interacting galaxies, UGC 05028 (the smaller face-on spiral galaxy) and UGC 05029 (the larger face-on spiral). Likely due to its gravitational dance with its larger partner, UGC 05028 has an asymmetric, irregular structure, wh.....»»
